The IS12 Data also converts network information to NMEA0183 format for easy export to other devices. IS12 Mega The IS12 Mega is an extremely flexible instrument that: • Repeats information from both Simrad network devices and third party NMEA0183 devices. • Converts Simrad instrument data to NMEA0183 format • Converts NMEA0183 navigation data to Simrad data format A single button press scrolls the display through 32 information pages and any unused pages can be switched off so that frequently used pages can be accessed most quickly. The information is displayed in large characters which are easy to read even from a distance. IS12 Remote Control/Alarm The IS12 Remote Controller/Alarm can be used to control all of the major functions of any IS12 instrument on the same network, including calibration and alarms functions. This means that all instruments, no matter where they are located, can be controlled from any convenient position. It can be used either as a handheld device or fixed to the dash. E04820 Issue 1.0 13 Introduction IS12 Data Introduction IS12 Instrument System • Part I – Introduction 1.3 The IS12 network system The IS12 system is built around Simrad’s proprietary high-speed bus networking system SimNet. This allows instruments to be easily interconnected and share data. All units are interconnected and powered using a standard single cable (Fig 1.2). WIND Tx MEGA DATA WIND SPEED/LOG DEPTH COMPASS REMOTE CONTROL COMPASS Tx Fig 1.2 - Example of an IS12 network system set-up Additional instruments can be added to the system to act as repeaters; for example, at the chart table of a sailboat or the flybridge of a powerboat. Thus, as shown in the example above, the Mega and Data Repeater instruments repeat the information from the main instruments. 14 E04820 Issue 1.0 Instruction Manual Part II IS12 COMBI 2.1 General As well as displaying depth and boat speed in whichever units you prefer, the IS12 Combi offers a host of additional features. Depth offsets, shallow and deep alarms and start timers are all adjustable, and additional information such as water temperature, cumulative log, trip log and race times are easily displayed at the press of a button. 2.2 Depth display When the IS12 Combi is switched on, the current water depth is shown on the top line of the display (Fig 2.1). The digits show the water depth below the boat. In this example, the depth is displayed in meters (M). COMBI FTM DEPTH SPEED HKts LIGHT ALARM TIMER UPPER INFO LOWER INFO Fig 2.1 - Default Combi display Note As a default, the Combi will display the depth below the transducer. An offset can be entered so that the display shows either the depth below the keel or the waterline depth.. ➞ Refer to section 3.3 for information on how to program a keel or waterline offset. 2.3 Depth alarms The IS12 Combi features an audible alarm function that can be set to alert if the water depth falls below or rises above a specified value. The shallow alarm will sound if the water depth falls below a specified amount, to warn if the boat is about to run E04820 Issue 1.0 15 Combi 2 OPERATION IS12 Instrument System • Part II – IS12 Combi aground and the deep alarm will sound if the water depth goes above a specified amount. Combi Note This function can also be used as a navigation tool when navigating using depth contours – by setting the shallow and depth alarms below and above the required contour depth, the alarm will sound if the boat strays off the contour.

Use the and keys to select, then press to set. The unit will then return to the main Calibration menu. 3.2 Damping The damping function adjusts the update rate of the display. A damping level of 0 (minimum) will cause the display to update rapidly, while a damping level of 4 (maximum) will result in a more stable display, but one that is less frequently updated. COMBI LIGHT UPPER INFO ALARM TIMER INFO Enter Calibration mode, press once (the display will show “CAL DPG”) and press (LOWER INFO). The damping level can be adjusted using the and keys (Fig 3.3). or Fig 3.3 Adjusting damping To set the selected damping level, press . The display will then return to the main Calibration menu. 3.3 Depth offset As a default, the Depth Sounder displays the water depth between the transducer and the sea bed. However, for boats such as sailing yachts with a keel, it is more useful for the display to show the available water below the keel, which is sometimes as much as 2m (6.5ft) below the transducer. In other circumstances it may be more important to show the waterline depth, that is the total depth of water from the bottom to the surface. E04820 Issue 1.0 19 IS12 Instrument System • Part II – IS12 Combi The IS12 Depth Sounder allows a keel or waterline offset to be entered, so that the displayed depth will more accurately reflect the depth of water available beneath the boat. Waterline Depth transducer Depth below keel Depth below Keel Offset Waterline Offset Combi To calculate the offset amount, measure the vertical distance between the bottom of the keel and the bottom of the transducer for a keel offset, or the vertical distance between the surface of the water and the bottom of the transducer for a waterline offset (Fig 3.4). Fig 3.4 - Depth offset Note The offset amount will be in the same units as selected in section 3.1. To enter the offset, enter Calibration mode then press twice (the display will show “CAL OFST”) and press . The current offset will be displayed – the default value is 0.0. 3.3.1 Keel offset Since entering a keel offset is reducing the displayed depth, this is entered using the key, which will adjust the offset in 0.1m/ 0.1ft decrements. To confirm the selected keel offset, press . The display will then return to the main Calibration menu. 3.3.2 Waterline offset A waterline offset increases the displayed depth, this is entered using the key and adjusts the offset in 0.1m/0.1ft increments. Confirm the selected waterline offset by pressing . The display will then return to the main Calibration menu. 3.4 Switching the depth transducer off/on If the boat is also fitted with a fishfinder running at a different frequency, there may be some interference between the two 20 E04820 Issue 1.0 Instruction Manual depth transducers. In this case, the transducer can be switched off. This is also useful to conserve power when on a long ocean crossing, where the Depth Sounder is not needed. Enter Calibration mode, press three times (the display will show “CAL TRAN”) and press . 3.5 Speed sensor calibration When the IS12 Combi is first installed, it is important that the speed sensor is calibrated properly, as different boats with different hull shapes and characteristics can give a slightly different speed reading to the actual speed through the water. Enter Calibration mode, press four times (the display will show “CAL SPD”) and press . Two speed calibration options are then available by pressing or . The first option is calibration by percentage correction (section 3.5.1), which can be performed at the dockside or at sea. The second is calibration by “measured mile” (section 3.5.2), which must be performed at sea. Either one of these can be used to calibrate the Speed Log. 3.5.1 Percentage correction This method can be used if the displayed speed and the actual speed vary by a certain ratio. For example: Actual Boat Speed = 6 kts Displayed Boat Speed = 5 kts Actual Error = Displayed x 100 = 120% Therefore, a percentage correction of 120% must be entered: Select the “ ” option in the Speed Cal menu and press . The display will show the current boat speed and correction percentage on the display. Use the and keys to adjust the percentage correction to the required level and press to set. The display will then return to the main Calibration menu. E04820 Issue 1.0 21 Combi The display will show “ON”. To turn the transducer off, press the or key (the display will show “OFF”), then press to confirm. The display will then return to the main Calibration menu. While the transducer is set to off, the main depth display will show “OFF”. To turn the transducer back on again repeat the above procedure. IS12 Instrument System • Part II – IS12 Combi 3.5.2 “Measured mile” Combi This procedure automatically calibrates the speed sensor by measuring the average time to cover a known distance and com-paring this with the time it should have taken to cover this distance at the measured boat speed (Fig 3.5). The error is automatically calculated and used to adjust the speed sensor data. Measured Boat Speed is compared to the Calculated Boat Speed over a measured distance Fig 3.5 - Calibrating boat speed over measured mile Select the “LEG1” option in the Speed Cal menu. Do not press at this point. COMBI LIGHT TIMER RESET INFO Fig 3.6 - “Measured mile” calibration display COMBI The display will show “– – –” and “LEG1” (Fig 3.6). When the boat reaches the start of the measured distance, press the key – the display will show “RUN”. Press the key to cancel the calibration at any point. At the end of the measured distance run, press . The display will show “END”. To calibrate the log based on the Leg 1 run only press again – the display will then exit to the main Calibration menu. To re-run Leg 1 again, press repeat the above procedure. LIGHT ALARM TIMER UPPER INFO LOWER INFO or to select “LEG1” and For maximum accuracy, the run should be repeated in the opposite direction – press or to select “LEG2” (Fig 3.7) and repeat the above procedure.

For this purpose a compass angle offset can be entered. Enter Calibration mode and press twice to select “OFST” and press (LOCK). The display will show the current offset entered (factory default is 0°). Press to offset the displayed heading counterclockwise (1° per press), or to offset the heading clockwise (Fig 15.4). The display will show “-” for an counterclockwise offset and “+” for a clockwise offset. Press to confirm the offset entered and return to the Calibration mode menu. 15.4 Transducer calibration Compass Before using the IS12 Compass, the transducer must be calibrated to compensate for any magnetic deviation caused by ferrous or magnetic objects surrounding it on the boat, such as cockpit speakers, etc. 1. With the boat motoring along slowly (2–3 knots) in calm conditions turn the wheel to induce a slow rotation of the boat in either direction (approx. 4°/sec). 2. Enter Calibration mode and press three times to select “AUTO” and press (LOCK). The display will flash between “TURN” and “AUTO”. 3. Allow the boat to turn through a minimum of 1 1⁄4 turns (450°) in approximately 2 minutes, during which time the compass transducer will automatically calibrate itself. Increase speed/rate of turn Decrease speed/rate of turn Fig 15.6 Increase/decrease rate of turn 52 4. If the rate of turn is too high, the display will flash “LESS” indicating decrease the angle of turn – turn the wheel slightly to decrease the angle until the display flashes “TURN” and “AUTO” again. If the rate or turn or boat speed is too slow, the display will flash “MORE” indicating increase the angle of turn (Fig 15.6); turn the wheel slightly to increase the angle until the display flashes “TURN” and “AUTO” again. E04820 Issue 1.0 Instruction Manual If the calibration is successful, the display will show “PASS” and sound a long beep. If the calibration has failed, the display will show “FAIL” and sound an alarm – repeat the above procedure following the directions carefully. Press to save the autocalibration and return to the Calibration mode menu. If the compass will still not calibrate, then it is usually because the deviation being detected is too great, which may be due to the compass transducer being too close to a metallic or magnetic object (the minimum safe distance is 1 m [3 ft]). Move the transducer to a position as close to the ideal centerline location as possible, but away the from speakers, metallic superstructure, etc. Repeat the above procedure. Note This should only need to be done once when the transducer is first installed, unless the transducer is changed, repaired, relocated, or where any metallic objects have been installed or removed near to the transducer since it was calibrated. In the interests of accurate performance, always bear in mind the location of the transducer when installing any metallic objects on the boat. If in any doubt, recalibrate the compass transducer. 15.5 Magnetic/ true heading As a default, the compass will display the magnetic heading detected by the transducer. However, if the magnetic variation has been entered (see section 15.6), the display can also show the true heading. To set the display to show the true heading, enter Calibration mode and press four times to select “HDG” and press (LOCK). LIGHT LOCK Fig 15.6 - Toggling between displays The display will show the currently selected display: “MAG°”for magnetic heading, or “TRU°”for true heading (Fig 15.6). Press or to confirm. E04820 Issue 1.0 to toggle between the two options and press 53 Compass Note IS12 Instrument System • Part VI – IS12 Compass 15.6 Magnetic variation In order to be able to display the true heading (see section 15.5), it is necessary to enter the local magnetic variation, which is shown on charts of the area and is expressed as a number of de-grees east or west of the magnetic heading. To set the display to show the true heading, enter Calibration mode and press four times to select “M:VAR” and press (LOCK). The display will show the current magnetic variation entered (factory default is 0°). LIGHT LOCK Compass Fig 15.7 - Entering the local magnetic variation Press to enter an westerly variation (1° per press), or to enter an easterly variation (Fig 15.7). Press to confirm the variation entered and return to the main Calibration menu. Note As the local magnetic variation differs from region to region due to fluctuations in the earth’s magnetic field it is important to check the local variation as shown on charts during longer voyages and adjust this setting if required. Note If the Compass instrument is using an NMEA input to provide the heading information, the variation is automatically supplied and is displayed here, but is not adjustable. 15.7 Configuring the IS12 Compass on SimNet The Compass instrument can be configured to work with SimNet-capable data sources in two different ways: System mode – In this mode the heading data source for the Compass instrument can be configured by remote devices that have SimNet device configuration (such as SimNet Chartplotters) and are capable of commanding the Simrad group. StandAlone mode – This mode allows the Compass instrument to automatically select its own heading data source and cannot be configured by a remote device. Therefore, the Compass instrument will be locked to the same heading data source, until a change of SimNet mode or a mode reset occurs. The default mode is System mode. To check the mode at any time, enter the Calibration mode (see section 5 for details) and press to scroll through the calibration pages, until the display indicates the mode by showing “SYST” (System mode) or “S-A” (StandAlone mode). 54 E04820 Issue 1.0 Instruction Manual To ensure that the Compass instrument can lock on to the desired heading data source, the SimNet mode needs to be reset. This will only need to be done once during installation, unless a change of configuration, or a new heading data source is re-quired. 1. Choose a SimNet mode System mode – In this mode the Compass instrument automatically selects its own heading data source, but can be reconfigured by a remote device (i.e. a Sim-Net chartplotter), which is capable of commanding the Simrad group. StandAlone mode – this is where the Compass instrument automatically selects its own heading data source and is not able to be reconfigured by a remote device, only manually.

Press LIGHT to accept the changes and exit to the Calibration menu. 21.3 Operation modes Mega There are two modes of operation for the Mega instrument depending on the installation and equipment it is to be used alongside. 21.3.1 IS12 mode (Mode 1) This function allows the Mega to be used as part of an IS12 instrument system. In this mode, the Mega will display the following data: • IS12 data present on the system • Processed* navigational data via the IS12 network • Incoming navigational data via NMEA 0183 * i.e. any nav data received and converted to IS12 data format by another piece of equipment on the network. 70 E04820 Issue 1.0 Instruction Manual Note Note In this mode, any third-party navigational master units connected to the Mega via the NMEA In terminals will be repeated by the Mega display and this data will then be passed onto the IS12 network. Incoming NMEA instrument data (i.e. speed, depth, wind, etc.) cannot be displayed. Only one instrument can receive NMEA data in an IS12 instrument system. If the same item of data is already available on the IS12 network then the incoming NMEA sentence is not processed – IS12 network data always takes precedence over NMEA data. The NMEA Out terminals will transmit the following data: • IS12 instrument data. IS12 Instrument data & converted nav data NMEA In Nav data NMEA Out Instrument data Mega Fig 21.3 - Installation example: IS12 mode 21.3.2 NMEA mode (Mode 2) This mode should be selected, if the Mega instrument is to be used as an NMEA data repeater with no IS12 master units. In this mode, the Mega will display the following data: • NMEA 0183 instrument data • NMEA 0183 navigational data In this mode only the NMEA terminals are used to link the Mega E04820 Issue 1.0 71 IS12 Instrument System • Part VIII – IS12 Mega to any master units – the network ports are only used to supply power to the display. No data is received or transmitted to any IS12 units connected to the Mega via the network ports. The NMEA Out terminals will retransmit the following data: • NMEA 0183 instrument data • NMEA 0183 navigational data NMEA Out NMEA In Instrument & nav data 12V in Instrument & nav data Fig 21.4 - Installation example: NMEA mode Mega To switch between IS12 & NMEA modes, enter Calibration mode and press once (the display will show “MODE CAL”).

Local control means that any adjustments to lighting will only affect 74 E04820 Issue 1.0 Instruction Manual this specific instrument. With network control, all instruments in the network will be affected. The IS12 instruments are set to network lighting by default. To enter Calibration mode, press once (the display will show “LIGHT CAL”) and press (INFO). The top line will show the current setting – “NET” for Network or “LOC” for Local. The setting can be changed using the or key. To set the selected backlighting modes, press . The display will then return to the main menu. Note Press Note Any changes will affect the specific instrument only. to exit to the main Calibration menu at any point. 21.5 Configuring the IS12 Mega on SimNet The Mega instrument can be configured to work with SimNetcapable data sources in two different ways: The default mode is System mode. To check the mode at any time enter Calibration mode and press to scroll through the calibration pages, until the top line of the display indicates the mode by showing “SYST” (System mode) or “S-A” (Stand-Alone mode). To ensure that the Mega instrument can lock onto the desired data sources, the SimNet mode needs to be reset. This will only need to be done once during installation, unless a change of configuration, or a new selection of data sources is required. 1. Choose, which SimNet mode is required System mode – In this mode the Mega instrument automatically selects its own data sources, but can be reconfigured by a remote device (i.e. a SimNet chartplotter), which is capable of commanding the Simrad group. E04820 Issue 1.0 75 Mega System mode – In this mode all the data sources for the Mega instrument can be configured by remote devices that have built-in SimNet device configuration (such as SimNet chartplotters) and which are capable of commanding the Simrad group. StandAlone mode – This mode allows the Mega instrument to automatically select its own data sources and cannot be configured by a remote device. Therefore, the Mega instrument will be locked to the same data sources, until a change of SimNet mode or a mode reset occurs. IS12 Instrument System • Part VI – IS12 Mega StandAlone mode – This is where the Mega instrument automatically selects its own data sources and is not able to be reconfigured by a remote device. The Mega instrument will be locked on to the same data sources until a manual change of SimNet mode occurs. MEGA LIGHT • • INFO Fig 21.4 System mode 3. Start the autoselection process If System mode is required, then the Mega instrument must be powered up with the right-hand key (INFO) pressed. Making this selection will reset the data sources of all other IS12 repeater displays in System mode (Fig 21.4). MEGA LIGHT • • INFO Fig 21.5 StandAlone mode Mega Note 2. Choose, which data sources are required When a System or StandAlone reset is actioned, the IS12 Mega instrument starts to automatically look for and lock onto each data source (i.e. Depth, Speed, Heading, etc). If a particular data source is required for selection, then this must be the only data source of its type on the SimNet bus. To do this, remove any multiple sources from the bus just leaving the single data source that is required. If StandAlone mode is required, then the Mega instrument must be powered up with the left-hand key (LIGHTS) pressed (Fig 21.5). This selection will not reset any other IS12 data sources. Changing the mode (or even reselecting the same mode) will reset any data source selection the Mega instrument was pre-viously locked on to. 22 INSTALLATION Refer to Part X 76 E04820 Issue 1.0 Instruction Manual Part IX IS12 REMOTE CONTROL 23 OPERATION 23.1 General The IS12 Remote Control can be used to control all the major functions of any IS12 instrument that is on the same network, including calibration functions. The remote also repeats all alarms. 23.2 Selecting display Control of a specific instrument is accessed by pressing the ▼ key on the Remote Controller. This will select the first instrument on the network, indicated by “CTRL” flashing briefly on the instrument display (Fig 23.1). The unit selected can now be operated using the remote control. To select a different instrument, press the ▼ key repeatedly to cycle through the instruments on the network, until the required instrument is selected.

E04820 Issue 1.0 77 IS12 Instrument System • Part IX – IS12 Remote Control 23.3 Keypad configuration As the Remote Control is intended to control all instruments in the IS12 range, the keypad is a generic design, which applies to all IS12 instrument keypad layouts (Fig 23.2 indicates the respective key positions). Remote Note For installations where the instruments are rear mounted, the keypad will not be visible; please refer to the relevant user manual for the specific keypad layout. Fig 23.2 - Remote control key positions 23.4 Cancelling alarms The Remote Control will repeat any alarms sounded by the instruments in the network. To cancel the alarm, select the relevant instrument using the ▼ key and press the equivalent key on the Remote Control. ➞ Refer to the individual instruments regarding key sequences for cancelling alarms. 78 E04820 Issue 1.0 Instruction Manual 24 CALIBRATION 24.1 Disabling remote control On some installations it may be preferable to limit remote control access to only some instruments on the network, for example: 1. On a flybridge powerboat with a set of instruments on both steering stations, where some of the instruments would be out of sight of the Remote Control user (Fig 24.1). 2. On a sailboat with chart table repeaters. Some of the instruments would be out of sight of the Remote Control user, which would normally be positioned to control the cockpit instruments. 3. On a sailboat with a set of mast-mounted repeaters. Since these are more difficult to access, it may be preferable to limit remote control to these instruments only. Flybridge Front-mounted instruments – no remote control required Remote control disabled Main Steering Station Rear-mounted instruments – remote control required Remote control enabled Fig 24.1 - Typical system with partial remote control facility It is possible to disable the remote control facility on specific instruments, which will be “ignored” by the Remote Control.

On an installation where some instruments are rear mounted and a remote control is needed to control these only. IS12 Instrument System • Part IX – IS12 Remote Control 24.2 Re-enabling control on rear-mounted instruments Once the remote control facility has been disabled on an IS12 instrument, this can normally only be re-enabled using the instrument’s own keypad, since the Remote Controller will now be unable to access that instrument. In the event that the remote control facility has been accidentally disabled on a rear-mounted instrument (where the keypad is not accessible), the following procedure will allow remote control access to all instruments on the network: With the power to the system off, press and hold the ▼ key on the Remote Control while turning the power on (Fig 24.2). POWER OFF POWER ON Remote Fig 24.2 - Overriding system remote control settings The Remote Control will now temporarily be able to access all instruments on the network, even those which have the remote control facility disabled. Select the instrument which has been incorrectly disabled and re-enable the remote control facility through the Calibration menu. Note 80 This procedure temporarily overrides the remote control facility settings. If the power is then switched off and on again without changing the remote control setting on the instrument in question first, the instrument will revert to its previous settings. E04820 Issue 1.0 Instruction Manual 25 INSTALLATION 25.1 Installation The Remote Control/Alarm is supplied with a dash-mount clip and can be used as a fixed or a handheld control unit. The cable can either be fed directly through the hole in the dash-mount clip, so that it is out of sight when the remote control is in the clip, or it can be routed externally through the channel at the bottom of the clip, then back up and through the dash clip, which may be more convenient if using the remote control as a handheld device (Fig 25.1). Concealed cable (fixed mount) Exposed cable (handheld) Fig 25.1 - Cable routing options Note The channel at the bottom of the dash clip for externally routing the cable is normally blanked off – this can be opened up using a sharp knife or scalpel if required (Fig 25.2). Cut out cable channel Remote Fig 25.2 - Dash-mount clip, bottom view – cable channel The unit is supplied with a self-adhesive drilling template; fix this in the required position and drill the four 2.5 mm screw holes and the 11 mm hole for the cable if required (see Fig 25.1 above). If fixing to GRP, countersink the four screw holes to avoid splitting the gelcoat when fitting the self-tapping screws supplied. Fit the dash-mount clip, feed the cable as required, and fit the Remote Control into the clip. E04820 Issue 1.0 81 IS12 Instrument System • Part IX – IS12 Remote Control 25.2 Electrical installation The Remote Control is fitted with a 2 m cable with an IS12 connector fitted to the end. Simply locate a spare port in a conveniently located instrument and plug in. If a spare port is not available an SDJ three-way joiner, available as a separate accessory can be added along with an additional data cable to provide a spare port (Fig 25.3). SDJ ThreeWay Joiner Additional Data Cable Fig 25.3 - Using an SDJ three-way joiner to connect the Remote Control to a system 25.3 Unclipping the Remote Control Remote To remove the Remote Control from the dash-mount clip, hold the top of the unit and pull it out of the clip (Fig 25.4). Fig 25.4 - Removing the remote control from the dash-mount clip 82 E04820 Issue 1.0 Instruction Manual Part X IS12 INSTALLATION 26 INSTRUMENT HEAD 26.1 General All IS12 instrument heads are a standard 110 x 110 mm (4.3 x 4.3 in) size and can be mounted either from the front or the rear. 26.1.1 Front mounting Fig 26.1 Front mounting 35mm (1.4in) minimum Front mounting (Fig 26.1) is the standard method of fitting and is the most straightforward. When mounting the instrument head, it is important to ensure that there is adequate clearance behind the bulkhead for the rear of the instrument with the cables inserted – allow at least 35 mm (1.4 in) clearance (Fig 26.2). In addition, the instrument should not be fitted to a surface that has a curve greater than 1 mm (1⁄25 in) across the mounting area. If fixing to an uneven surface, care should be taken not to overtighten the screws. When choosing a location, consideration should be given to the water integrity of the gasket seal if the surface is not flat. The IS12 is designed to be weatherproof, but the rear of the instrument case with its electrical connections should be protected from moisture as far as possible. Tools required for installation: - Drill - 2.5 mm (0.09 in) drill bit - 86 mm (3.4 in) hole saw - Countersinking bit Fig 26.2 Clearance required behind bulkhead Note Long term exposure to direct sunlight can damage the liquid crystal display, if left unprotected when not in use – always use the instrument cover supplied. Fig 26.3 - Fitting keypad and bezel E04820 Issue 1.0 The easiest way to fit the keypad and the bezel to the installed instrument head is to locate the keypad in the keyholes in the bezel and then offer this up to the instrument head, angling the bezel back slightly to prevent the keypad falling out. The bezel should click into place when located correctly (Fig 26.3). 83 Installation Using the self-adhesive template supplied drill the central aperture for the instrument case using the hole saw, then the four fixing holes as indicated on the template. If the instruments are to be fixed to a GRP bulkhead, the fixing holes should be countersunk after drilling to stop the screws splitting the gelcoat. The instrument is 110 mm (4.33 in) square, but a distance of at least 6 mm (0.25 in) should be allowed between adjacent units for the protective instrument cover supplied. IS12 Instrument System • Part X – IS12 Installation To remove the bezel, simply lift the top edge of the bezel slightly to disengage the locking clips and pull away from the instrument head (see Fig 26.4). Fig 26.4 - Removing the bezel 26.1.2 Rear mounting When the instrument is rear mounted, only the display can be seen, the main body of the instrument, including the keypad, is hidden behind the panel. This is a more elegant method of installation, but does require precise cutting of the apertures into the bulkhead or dashboard. It is therefore recommended that installation is done by a professional marine installer. Fig 26.5 Rear mounting The instrument can be fixed to the panel using either the self-tapping screws supplied (if the panel is thick enough), or 2 mm studs fixed to the rear of the panel which align with the four fixing holes. (Fig. 26.5). Tools required for installation: - Drill - 5 mm (0.2 in) drill bit - A fine toothed file - Fretsaw Installation To assist in cutting a precise aperture for the display, a self- adhesive template is supplied with the unit. Fix the template in the correct position and drill 4x 5 mm holes on the waste side of the four corners of the aperture. Starting from one of these holes, carefully cut along the dotted line around the four edges. To ensure the hole is a good fit, cut slightly inside the line (on the waste side) and then use the file to smoothen the edges until the display fits precisely. Note Because the keypad is not accessible with this method of mounting, the Remote Control unit (see part IX) will be required to enable control of instrument functions. 27 TRANSDUCERS 27.1 IS12 Speed/Depth transducer Note 84 Please refer to manufacturer’s installation instructions supplied with the transducer. E04820 Issue 1.0 Instruction Manual 27.2 IS12 Wind transducer installation 27.2.1 Running the cable It is easiest to run the transducer cable if the mast is stepped. If this is not possible, all necessary precautions should be taken – always use a bosuns chair and ensure all tools are securely attached when working aloft. Apply the self-adhesive template supplied to the masthead, pointing fore–aft. Drill the fixing and cable exit holes as marked – the masthead bracket incorporates a cable clamp to secure the transducer cable and provide strain relief (Fig 27.1). Cable clamp channels Allow 75mm (3.0") of cable at the masthead Gasket MASTHEAD Cable exit point Mast Top Cable Exit Fig 27.1 - Drilling exit hole for transducer cable Note The cable can be fed through the side of the mast if this is more convenient. Mast Side Cable Exit Cut out blanking piece Fig 27.2 - Cable channel exit points BOW It is recommended that a grommet is used to avoid damage the cable where it passes through the mast. Allow at least 75 mm (3.0 in) of cable at the masthead for the transducer connection. For boats with an aluminium mast, a channel is normally provided inside the mast section for running electrical cables. This will usually have a tag line or “mouse” (i.e. a length of line running the length of the mast to assist in pulling through cables). If not, the cable will need to be fed down and drawn out the bottom by hand. For boats with a wooden mast the cable can be run down the outside of the mast held in place with galvanised cable clips. 20mm (0.78") Fig 27.3 - Fitting the masthead bracket E04820 Issue 1.0 1. Route the transducer cable in the strain relief channels in the bracket and out the back. If the cable exits through the side of the mast, route the cable in one of the blanked off side channels and out the back (Fig 27.2). 2. Use a sharp knife or scalpel to remove the blanking piece and open up the channel. 3. Attach the masthead bracket with the screws provided. Ensure the bracket is mounted the correct way round, so that the wand will be pointing in the correct direction (Fig 27.3). The transducer can be mounted facing aft if required, but it will be necessary to set the transducer orientation to “AFT” in the Calibration menu (see section 15.2 for more details). 85 Installation 35mm (1.38") 27.2.2 Fitting the masthead bracket IS12 Instrument System • Part X – IS12 Installation 27.2.3 Assembling the transducer The vane and cups assemblies are packed separately; fit the vane to the transducer so that the shaft on the top of the transducer fits correctly into the vane (the shaft is keyed so that it will be aligned correctly). Screw the counterweight in just far enough to lock the vane into place (Fig 27.4). 1) Fit the vane Ensure the shaft is oriented correctly 2) Screw in counterweight (do not overtighten) Fig 27.4 - Attaching the wind vane Note Check that the vane rotates freely – do not overtighten the counterweight or it may restrict the vane’s movement. The anemometer cups fit to the base of the transducer body in a similar way (Fig 27.5). Ensure the cups are pushed fully home on the spindle. Once fitted, they are held in place by a grub screw, which should be tightened (using the Allen key supplied) enough to hold the cups in place without restricting their movement. Note Check that the cups rotate freely. 1) Fit the cups 2) Tighten grubscrew Fig 27.5 - Attaching anemometer cups Installation 27.2.4 Attaching/removing the transducer The masthead transducer is attached to the masthead bracket using a simple quick-release clamp system. 1. Slide the locating pegs on the rear of the transducer base into the slots on the masthead bracket. 2. Rotate the transducer down onto the masthead bracket. 3. The transducer base will then lock into place (Fig 27.6 page 87). Caution 86 Ensure the quick-release clip is properly engaged by pulling it fully forward.

Note To avoid damage, it is recommended that the masthead transducer be taken down at the end of the season if the boat is to be laid up or lifted out. Simply remove the transducer cable, pull the release clip back and lift the transducer off the masthead bracket (Fig 27.7). Lift 1 2 Pull back Fig 27.7 - Removing masthead transducer Caution To avoid corrosion of the electrical contacts, always fit the cover supplied over the end of the masthead cable. Note If the boat is fitted with more than one IS12 instrument, it should be noted that it is not necessary to plug the transducer cable directly into the back of the instrument – any spare network port can be used. The compass should be positioned as close to the centerline of the boat as possible (Fig 27.8), in one of four possible orientations. If the boat is GRP or wooden, the compass can be mounted below deck, but must be at least 1 m (3 ft) away from any metallic objects such as stereo speakers, heating units, etc. Fig 27.8 Ideal Compass transducer location E04820 Issue 1.0 If the boat has a metal hull (this includes ferro-cement), the compass must be mounted on a mast or pole between 1 and 2 meters (3–7 ft) above deck. 87 Installation 27.3 Compass transducer IS12 Instrument System • Part X – IS12 Installation When mounting, make sure that the compass is the right way up and is level.

Alternatively, heading information may be supplied from an external source via the NMEA input. The two terminals on the rear of the unit (see Fig 28.10,) are marked NMEA IN + (Data) and NMEA IN - (Common). These should be connected to the NMEA OUT connections of the interfaced equipment. The IS12 Compass can process the following NMEA sentences: HDG VHW Note Mag heading, plus deviation and variation Heading, Mag, and True The Compass transducer should not be used if heading data is being supplied via the NMEA input. Fig 28.10 - NMEA In connections 28.1.6 IS12 Data (NMEA Out) Installation The Data instrument features an NMEA0183 output – the Data instrument is interfaced to external equipment using the crimp terminals supplied. The two terminals on the rear of the unit (Fig 28.11) are marked NMEA OUT + (Data) and NMEA OUT - (Common). These should be connected to the NMEA IN connections of the interfaced equipment. Fig 28.11 - NMEA Out connections 28.1.7 IS12 Mega The Mega instrument features an NMEA0183 input and output, and is interfaced to external equipment using the crimp terminals supplied. The two terminals on the rear of the unit marked NMEA OUT + (Data) and NMEA OUT - (Common) should be connected to 90 E04820 Issue 1.0 Instruction Manual the NMEA IN connections of the interfaced equipment. The two terminals marked NMEA IN + (Data) and NMEA IN - (Common) should be connected to the NMEA OUT connections of the interfaced equipment (Fig 28.12). Fig 28.12 - Mega NMEA connections When in IS12 mode, the Mega can receive and display incoming navigational data via NMEA (not NMEA instrument data!) and will output IS12 instrument data (depending on the master units in the system). ➞ For further details of NMEA sentences received/transmitted, see section 21.3.4. Note Only one instrument per IS12 system can input NMEA data. The Mega instrument can be used as a stand-alone NMEA repeater outputting/receiving with no IS12 master units. If using the Mega in this way, the operation mode should be set to NMEA Mode 2 (see section 21.3.2). 28.7 Electronic interference suppression IS12 has been designed to minimize the effects of interference generated by the engine alternator. However, precautions should still be taken by routing the cables away from the engine compartment. Do not run the cables down trunking carrying high current cables. The transducer cable should also be kept separate from the boat’s radio antenna cable if possible. 28.8 Magnetic interference Deviation of the main ship’s compass is caused by objects which interfere with the earth’s magnetic field being placed in its near proximity. E04820 Issue 1.0 91 Installation Engines with spark ignition—also some refrigerators—should be fitted with suppressors. Your local agent should be able to advise on this and supply suppression kits where necessary. IS12 Instrument System • Part X – IS12 Installation Normally a safe distance for instrument installation would be 30 cm (1 ft) from the ship’s main compass. For safety reasons it is recommended that a check is carried out; temporarily situate the working display in the proposed position to ascertain the effect that the instrument might have on the particular ship’s compass while in operation. 29 NETWORK 29.1 Installing an IS12 network IS12 instruments are “daisy chained” together, with each instrument linking to the previous one by a single cable carrying power and data (Fig 29.1). Fig 29.1 - IS12 “Daisy chain” cable system The cable plugs into either of the two circular network ports on the rear of the instrument. The cable connectors are keyed so that they will always be correctly oriented when inserting the cable into the instrument – the flattened edge of the connector should be facing down when inserting (see Fig 29.2). Network bus ports Flattened edge Fig 29.2 - Rear connections The first link in the IS12 system is the power cable, which should be connected to the boat’s 12V DC supply via a 3 Amp breaker or fuse as follows: Installation Red wire 12V DC Black wire - 0V Note Only one power cable is required in an IS12 system, but power must be supplied via an IS12 power cable (with a red connector end), or the system will not function. 29.1.2 Network termination Fig 29.3 Network terminator 92 The IS12 system is based around a high-speed data bus network. Although this is very robust, on very large or complex systems with many instruments the system may need to be properly terminated to ensure the integrity of the network. For this purpose a network terminator (Fig 29.3) is supplied with E04820 Issue 1.0 Instruction Manual some IS12 instruments. The terminator simply plugs into the last free network port in the daisychain. The terminator only needs to be fitted under certain circumstances. The terminator is not required if: a) The Compass instrument is used as a stand-alone instrument (and no other IS12 instruments are fitted). b) There is already a terminator fitted to the system. There should only be one terminator fitted per system. c) The system includes an IS12 Wind transducer. The Wind transducer has an inbuilt network terminator. d) The total system cable length (excl. the power cable) is less than 5 m. A small system does not require a terminator. If the installation does not meet any of the above criteria, the terminator should be fitted to the spare network port at the end of the longest cable run. Any unterminated spurs created using the SDJ three-way joiner must be less than 5 m (16.4 ft) in length (see Fig 29.4). Terminator fitted to end of longest spur Spur max cable length 5 m Three-way joiner SDJ Fig 29.4 - Creating cable spurs using SDJ three-way joiner Fold wire end back Ensure bare wires are not visible Fig 29.5 - Crimp terminals E04820 Issue 1.0 To ensure a good connection when fitting the terminals to the interface cable, fold back the exposed wires over the insulation before inserting into the terminal (Fig 28.5). Use a good quality crimp tool to crimp the terminals. 93 Installation Spur max cable length 5 m Instruction Manual Part XI APPENDIX 30 ADDITIONAL INFORMATION 30.1 Troubleshooting General Symptoms Possible cause Remedy No display on any heads in the system • Faulty connection to power • Fuse has blown • Check power connection • Replace fuse and check power supply current No display on one or more heads in system • IS12 data cable loose or broken • Check cable linked to first faulty unit.
